for The last four years meteorological organization (WMO) and the World, the warmest since records began nearly 170 years. 2018 was the fourth-warmest year, announced the organization on Wednesday and confirmed before the say US weather Agency NOAA. The average surface temperature was 1.0 degree Celsius above average in the pre-industrial era (1850-1900).

The years 2015 and 2017 were 1.1 degrees above the Mediterranean. The record data according to WMO, the year 2016 with an increase of 1.2 degrees above the pre-industrial Mediterranean. In the year, meteorologists have observed an unusually strong El Niño effect. With the every couple of years, so there weather phenomenon, El Niño, changes in wind currents and water temperatures go hand in hand in the Pacific that affect the weather in large Parts of the earth.

“Clear signs of the ongoing climate change,”

The collections of heat records were “a clear indication of the continuing long-term climate change,” writes the WMO according to analysis of data from five well-known data. The 20 warmest years were in the past 22 years, said WMO Secretary-General Petteri Taalas. “The reduction of greenhouse gases and climate change adaptation measures around the world must be a priority,” he said. By the concentration of man-made greenhouse gases in the earth’s atmosphere, which is at record levels, it accumulates in the heat on the earth.

Wrong arguments in the climate debate

“There are good reasons for a speed of 130 km on highways, climate change is not one of them”

“Single years count less than the Trend, and shows up,” said Taalas. “The warming in the past four years has been exceptional, both on Land and in the ocean.” The higher average temperature and record concentrations of CO2 in the earth’s atmosphere have massive consequences. “Many countries and millions of people have experienced to 2018, extreme weather events, with devastating consequences for the economy and the Ecosystem.”

Also in 2019 is already extreme weather: Australia is in the southern hemisphere, where summer is, have experienced the warmest January since records began, the offshore island of Tasmania and the driest January. In the USA, there have been at the same time to extreme cold. “The cold weather in the Eastern United States does not disprove the climate change,” says Taalas. The Arctic is warming twice as fast as all regions of the world, on average, ice melt, and such changes have influenced the climate. The changes in the Arctic might have contributed to the cold snap.
